Deeper analysis

CVE-2024-30547 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling DOM-based Cross-Site Scripting (XSS), in the Shazdeh Header Image Slider WordPress plugin (header-image-slider). This issue affects all versions of the plugin from n/a through 0.3 and is classified under CWE-79.

The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating it is exploitable over the network with low attack complexity and no required privileges, though user interaction is necessary. Remote attackers can trick users into performing actions, such as visiting a malicious site or interacting with crafted content, leading to DOM-based XSS execution in the victim's browser. This results in limited impacts on confidentiality, integrity, and availability, but with a changed scope due to the cross-origin context.

The Patchstack advisory at https://patchstack.com/database/wordpress/plugin/header-image-slider/vulnerability/wordpress-header-image-slider-plugin-0-3-cross-site-scripting-xss-vulnerability?_s_id=cve provides details on the vulnerability in the Header Image Slider plugin version 0.3. Security practitioners should review this reference for recommended mitigations, such as updating to a patched version if available.
